Car Speed from km/h to m/s

Question

The speed of a car at 80km/h corresponds to 100m/s. if the car is travelling at 210km/h how far does it travel in m/s?

Answer 1

Madison,

 

The information in the problem statement is not correct.  80 km/hr does not correspond to 100 m/s.

 

80 km/hr = [(80 km)*(1000 m/km)] / [(1 hr)(3600 s/hr)] = (80,000 m) / (3600 s) = 22.22 m/s

 

 

 

 

Answer 2

 First, we must determine the relationship between km per hour and meters per sec.
